WHEEL-RIM.

provements that are especially designed for holding pneumatic tires'on their rims and for conveniently removing them from the rim, primarily has for its object to provide an improved means of the character stated, which, when applied, tire on the rim and w iclt is adapted for suchadjustments whereby a quick and easy removal of the tire, in its punctured or in- ;lated condition, from the. wheel, is provided The usual method of reroving tires, in other types of rim structures for automobile wheel's, is to crowd the tire over the edge of the rim in taking the same on and oil. This method requires a lot ofexertion and is an operation alniost'impossible for women to'a'ccomplish, even with the present types of demountable rims nowin use, since in the latter, there are a lot of threaded bolts andnuts to adjust that requires time and exertion, and even after the demountable rim. is removed from the wheel, it still requires considerable labor to re-' move the tire-from the rlm, wh1chmust be dons- ,1,0 repair thev inner tube.

- otherrob'ects my inventionis especiallydesigned imoing away with the usual trouble and time required for removing the tire ,from the, wheel, and at the same timematerially add to the life of the tire by reason of removing the danger of damaging the tire and the tube, incident in the use of tire irons commonly required to removethe tire from the rim.

Another object of my invention is to provide, in a tire rim structure, a means for locking the rim parts to their tire securing position, so constructed that the operation the tire, are not hindered by mud or other. foreign matter that may clog on the wheel- Again, my invention seeks to provide an' improved vehicle rim construction of the general character stated that can be run without a tire thereon Without damaging Specification of Letters Patent.

\Vith other objects in View that wii 1 inafter appear, my invention nho peculiar features of consti ction 1 i. bination of parts fully out L pended desorption and claims trated in detail in the accompaay ings, in which: 7

Fig. 6 is a similar View that shows said locking ring at the unlocked po io" Fig. 7 is a detail View of one of the ing lugs or pins.

Fig. 8 is a. cross section of the rim with the tire thereon and illustrates mar of applying the removable 'ciencher I straight) rim member.

Fig. 9 is a detail view portion of locking ring, and

Fig. 10- is a detail view that the detent for holding the ice its locked position.

Fig. 11 is a detail view of mod I of key hole slot in the locking r Essentiaily, my tion consi improved torn 1o)? lock tire, and the said element s of a fiat ring 1 that is format of keyhole slots 10 for cooper. corresponding series stud key no that project laterally from that side rficleiicher shaped clamping rim ms .is applied.

By referring to Figs. 3, a and 8, noticodthat the key studs 2 are in of bolts 20 that pass through the annularly enlarged portion provided i an annular groove '21 that divides the enlarged portion into inner and outer int:

of like diameter the inner ones 15 7 a which lit the corresponding series of op ertures in the removable straight or clencher rim section l, it being understood that the inner lugQQ is made of the same dian'ieter as that of the outer lug 23, since the'apertures ill), in the rim section at must be large enough to slip the rim section l over the outer end oi the key bolt when pull ing the rim sections together, see Fig. 8.

The looiring ring 1 is of a thieknessi'or snugly riding upon the shanks 24 formed by the grooves 21, so that in turning the ring 1 i shown, the operation oi rotating the locking ring is greatly facilitated.

.L hey slots in the ring 1 may be formed with losed ends, as in Fig. ll, or open at the hole end, as shown in Figs. 1, :2, 5 and ii, the latter form of slot being preferable, since by having the hole portion of the slot open. up through the periphery of tlie'ring, the angle edge a; thereof, acts as a cutter as it cuts through or shears oil calred mud or other particles that may be on the wheel folly,

Tillie loclring'neys or lugs, serve a double 'ouroose 1n l'ioldine the detachable sl'rai ht i. Q I e:

in men'iber from. rotating or or clcnclier r1 movuw about on the wheel by and also in 1' serve to hold the locking ring, in place, there-- holding the said clenclicr or straight rim member against the wheel and, it should be stated, that since the clencher or straight rim member is of less thickness than the length of the inner stud on which the said rim member is mounted, a suilicient space is left between the said clencher or straight rim member and the wheel face, when the parts are assembled, to permit an easy r0- tation and removing of the various parts when a puncture occurs and consequent presis released from the lugs.

111 my coi'istruction of rim, when the tire is ii'iliated, the pressiju'e firmly forces the clencher or straight rim member out against the locking ring, which, in turn, is firmly pressed against the outer key studs 0r lugs 23, which. secures all parts in place.

To hold the locking ring from working back out of place-while running, an adjustable detent, preferably a snap spring, 7, is

pivotally attached to the loching ring with its free end adapted for engaging the adjecent one of the loci; studs, l ig. 10, it be ing obvious that when it is desired to rotate the locking ring to release the parts, the detent 7 is swung down indicated in Fig. 6.

From the foregoing description taken in connection with the drawings, the complete construction and the advantages of my invention will be readily understood.

The parts being operatively assembled, the locking ring having the position shown in Fig, 5, toidemount the tire, all that is necessary is to swing down the latch or detent and then turn the ring 1 in the direction of arrow on Fig. (5 until the hole parts of the key slots come over the locking studs and, when in that position, the locking ring, can be readily lifted out from the wheel and the tire, inflated or down, can then be quickly slipped laterally oil the beariugrim member, which is quickly done, since there is nothing to interfere with its removal. 1

What I claim is:

1. In con'ibination with a folly and a tire mounted thereon; a tire base engaging rim member fixed on the folly, a second tire base engaging member normally held under tire pressure and spaced from the adjacent side and a latch device in engagement with the ring and the said holding means for retaining said ring against displzicement.

3. Inconibination with a folly; a tire base engaging rim member fixed on the telly, n second tire base engnging member,

means for removubly holding, said second member against rotation, a locking ring cooperative with said holding means fortretaining the said second rim member against lateral displacement, said ring having a key hole slot engagement withthesaid retaining means, and a spring snapdetent.

mounted on the ring and adapted for engagemeut, with the. said holding means for;

retaining the said ring at its rim-holding position. i i

l. The combination of the wheel felly, a tire base engaging rimmember fixedly held on the folly, a second tire base engaging member, means on the. folly for holding said second tire engaging member against rotation and iroiu'contact with the folly and a locking ring cooperative with the. said holding means for retaining the said seconl tire engaging member against lateral displacement, said holding means including a plurality of cireumt'erentially arranged headed h key stud and a latch device on the ring for engaging an aejaeent key stud to hold the locking ring to the locked position, said keyhole slots opening outwardly at the periphery of the ring and provided with a dirt deflecting sl'iearing edge.

As an improvement in rims for motor vehicle wheels, the combination with the Wheel telly, a tire base engaging rim memher fixed on the telly, a series of circumferentially arranged key studs projected from the face of the telly and a second tire base engaging; rim member endwise slida'ble onto or oii' the key studs of a locking ring that fits against the said second tire engaging member, the said locking ring having cireumferentially arranged key hole slots cooperative with the key stud, the said slots at their hole ends opening through the outer edge of the ring whereby to produce a mud shearing or euttin edge when the ring is turned to release mm the key studs.

6. As an improvement in rims for motor vehicle wheels, the combination with the wheel felly, a tire base engaging rim mem ber fixed on the telly, aseries of circumferentially arranged key studs projected from the face of the telly and a second tire base engaging rim member endwise slidable onto or off the key studs; of a locking ring that fits against the said second tire engaging member, the said locking ring having cireumferentially arranged key hole slots cooperative with the key stud, and a spring snap latch pivotally mounted on the locking ring and adapted for engagement with one of the key studs to hold the ring against r'otation.
